4 Band Resistor Color Coding Reference Chart

4 Band resistor color coding chart is used to find the value of 4 band resistor.

How to use it

The first band of the resistor is the first significant number of resistance. The second band represents the second significant number of resistance. Whereas the third band is a multiplier. Finally, the fourth column represents the tolerance value of resistors.

Which side is right

Many resistors in the market have their tolerance band either in gold or silver color and one can easily find which side is right and from where to start decoding. However, a problem arises if the tolerance band is colored brown. For example, consider the case below:

Both end bands are brown. However, we can easily identify the tolerance band by measuring the distance of bands. The tolerance band is always designed apart whereas the other bands are located closer to each other.
